Kuto had always been a grumpy child. His parents had tried everything to make him happy, but nothing seemed to work. When he was old enough, Kuto left his home in Serbia and went out into the world to find his own way. He quickly learned that the world was not a friendly place. People were always trying to take advantage of him or hurt him in some way. The only thing that made Kuto feel better was getting revenge on those who wronged him.
As he got older, Kuto's anger only grew stronger. He began to get into fights more and more often, until it seemed like he was always looking for a fight. His hair turned black and he started wearing a black beanie hat pulled down low over his eyes so that people couldn't see how angry he really was. He shaved his face so that no one could see his expression when he was about to lash out at someone.
One day, Kuto finally snapped completely and went on a rampage through the city streets, attacking anyone who crossed his path with whatever weapon he could find - knives, clubs, anything that would inflict pain on others
